Sorry, I misunderstood your point - language and my reading
comprehension got in the way.
Based on the v1 review and your feedback, my proposed approach is a
small kdump_disable_features() in the x86 kdump code that checks
is_kdump_kernel() and clears the cap, called from setup_arch() after
parse_early_param(). This keeps the disable in x86 kdump code without
a parameter hook. Does that work for you?
